Question

If the volume of sphere is doubled then what is the capicitance

Answer 1

Answer:

The capacitance of a metal sphere is proportional to its radius (C=Q/V=R/ke), and its volume is proportional to radius cubed; therefore, the capacitance of a metal sphere is proportional to the cube root of the volume:31/3.

Answer 2

Answer:

The capacitance of an isolated sphere is: C = k • R , where k = constant

If the volume is tripled then the radius has increased by: ³√3

Therefore the capacitance increases by a factor of: ³√3.
